Hey Amy,
Regarding picking up stitches, I use one of two methods, either the crochet hook method which I find easier to use on finished garments that sprint a leak, so to speak, and using your knitting needle to hold the bottom stitch, and the bar above it, then passing the stitch over the bar and on up the run. I think those are the methods you are referencing. This topic, of course can get pretty involved since picking up decreases/increases, YOs and the like can get pretty complicated, which makes me think that maybe a brief discussion of "life lines" might be in order.
